This driver is copying CPU only. There are no cache operations involved!

I only thought using the bounce buffer here would be better than to add memcpy/memmove for alignment reasons in the driver (in terms of possible code duplication). I can of course implement this in a different way. Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
